JQuery multi step form validation

We are working on a multi step form, that already have been developped.

Actually, we are checking every informations via jquery, but sometimes, an error can happens on the server. So we are waiting the server response to validate, and in case of problem, we must display in an "one pag" of this form (without multi step then) the error displayed on the right input, with a red border and the error displayed.

There will be a second task still based on this after this work.

It have to be done in the next 48h.
Example of the running form will be given to let you know how it works.

Regards,
